Detailed Description
Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the utility model, its application, or uses.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
As shown in fig. 1 and 2, the utility model provides a well lid lifting tool, which comprises a handle 2 and a lifting rod 1, wherein the middle part of the handle 2 is connected with one end of the lifting rod 1, the other end of the lifting rod 1 is rotatably connected with a support rod 5 through a pin 4, the support rod 5 is parallel to the lifting rod 1, and one end of the support rod 5 is provided with a balancing weight 6, so that the support rod 5 is always downward under the action of the balancing weight 6.
The well lid lifting tool disclosed by the utility model can effectively and safely lift and pull the well lid and can prevent the well lid from slipping. As shown in fig. 3 and 4, when the manhole cover is used, the supporting rod 5 always downwards penetrates the lifting rod 1 and the supporting rod 5 through the water inlet hole under the action of the balancing weight 6, then the lifting rod 1 and the supporting rod 5 can have a certain angle by inclining, the supporting rod 5 can be abutted to the lower part of the water inlet hole by upwards lifting (the lifting rod 1 can be rotated in the lifting process, the supporting rod 5 and the water inlet hole are staggered, and the length of the supporting rod 5 is larger than that of the water inlet hole when the manhole cover is arranged), the contact area between the manhole cover and the manhole cover is increased, the supporting rod 5 can effectively prevent the manhole cover from falling off, and the safety of operators is ensured.
Furthermore, the handle 2 is detachably connected with the lifting rod 1. So that select suitable handle 2 according to actual conditions, for example when lighter well lid just can accomplish by one person and carry the operation, can select the handle 2 that is a bit shorter, when the well lid is heavier, needs many people to operate, can select the handle 2 that is a bit longer to many people carry and pull.
Furthermore, the two ends of the handle 2 are provided with anti-slip sleeves 3, and the anti-slip sleeves 3 are provided with anti-slip lines, so that the friction force between the palm and the handle 2 is increased, and the handle 2 is prevented from slipping and falling off closely.
Still further, the anti-slip sleeve 3 is made of rubber. The rubber material not only can effectively increase the friction between the palm and the grip 2, but also has certain elasticity and plays a certain role in protecting the palm.
Furthermore, the cross section of the stay bar 5 is semicircular, the cross section of one end, close to the stay bar 5, of the lifting rod 1 is also semicircular, the stay bar 5 is attached to the plane of the lifting rod 1, and the stay bar 5 and the lifting rod 1 are rotatably connected through the pin 4. When the stay bar 5 and the lifting rod 1 are round bars, the width of the overlapped part is large, and certain influence is possibly caused when the stay bar and the lifting rod pass through the water inlet hole.
Further, the distance between the pin 4 and the counterweight block 6 is greater than that between 1/2 and 2/3 of the support rod 5, so that the end, provided with the counterweight block 6, of the support rod 5 can be ensured to be always downward.
Further, the distance between the pin 4 and the counterweight 6 is equal to the distance between the pin 4 and the end of the lifting rod 1. Make the tip of vaulting pole 5 and the tip parallel and level of carrying pull rod 1, be favorable to carrying pull rod 1 to pass the inlet opening together with vaulting pole 5, avoided when carrying pull rod 1 or vaulting pole 5 pass the inlet opening, another person contradicts with the well lid.
Furthermore, the end of the support rod 5 far away from the counterweight block 6 is of an arc-shaped structure, so that when the support rod 5 rotates relative to the pin 4, collision between the end far away from the counterweight block 6 and the lifting rod 1 is avoided.
Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the utility model. The scope of the utility model is defined by the appended claims.
